Hi,
If you want to see your TIN as raw data, without interpolation and
conversion to gridded format, best to have it supported as a "mesh layer":
https://docs.qgis.org/3.4/en/docs/user_manual/working_with_mesh/mesh_properties.html
To add support for it, you need to have it in MDAL:
Hi,
I agree with Barend and Nicolas here.
It's a typical and essential question that we get all the time, like,
can we re-grid and subsample pixels ?
=>You can, technically, but you stay just within the same data,
and thus, create nothing new or meaningful.
In other words, it should not be done.
Hi,
You cannot invent new data between point without doing an interpolation. Your
choice of interpolation will determine the quality of this data. The only way
I can think of is to create a raster from this TIN. Then, resample
(re-interpolated) this raster with a finer pixel and then make a
?? a point in between what? A TIN is a set of triangles, where each corner
represents an X,Y,Z point in space (on a surface usually). So where do you nwat
to have and extra vertex...? Sounds like you are not wanting aq TIN in the end,
but something else...

Hi,
I am more interested to have a point in between rather than the triangles,
basically interpolate the data twice, to have an extra vertex between the
existing one.

The main question is actually: why would you want to do that? You just end up
with a larger data structure (more triangles) to show exactly the same surface
model. You would not have any more detail, i.e the smaller triangles inside the
original large one would have exactly the same azimuth and
Hi Experts,
I've tried so many software's without success.
Is it possible to upsample existing TIN? What I mean is for example divide
each triangle into two for example. Not interpolation but somehow...
subdivide or add more vertices between existing one?
Thank you for all your time
